There's just something about a KÃ¤stle. So stable (No. 1), so smooth, so powerful, so clean, you can feel how well made it is from the second you click in. Yes, it's expensive, but so is an Aston Martin. It's not the most versatile or forgiving, but when you get it to speed, railing arcs on groomed, snow from your downhill edge jetting into your shin, you won't want it any other way. The only unisex ski in the category (KÃ¤stle has yet to make a women's line), it boasts a wood core reinforced with metal that beams through chop and never falters. Cunningham: "The faster you go, the smoother it gets."
